V CONDENSER FOR MOTORVEHICLE RADIATORS.

Application filed June 21,

The object of the invention is to provide an appliance for us'e in connection with the radiators of motor vehicles, whereby the vapor, usually disappearing through the overflow, istrapped, condensed and automatically returned to the radiator, thus conserving the radiator contents which is par ticularly desirable where the radiator contains an anti-freezing solution, such as alcohol; to provide a construction wherein provision is made for the usual expansion of the radiator contents, when the vehicle engine is working, without exposing the same to evaporation; and toprovide a construction of this character which is of extremely simple form and therefore susceptible of manufacturing 3.Ild marketing at low cost.

' With this object in view, the invention consists in a construction and combination ofparts of which a preferred embodiment is illustrated in the accompanying drawings,

wherein: I Figure 1 is a side elevational view-of a motor vehicle radiator with the'invention 3 applied in operative position thereon.

Figure 2 is a longitudinal vertical 'section1 al view through the condenser chamber.

Figure 3 is an enlarged front elevational view of the condenser chamber. 7 I p In the application of the invention, the pipe 10 is connected to the radiator 11 and extends rearwardly from the radiator, the remote terminal being downturned, as inclicated at 12, and extending through-the top of a condenser chamber 14, the latter being closed and the downturned end '12 of the pipe being sealed at the oint where it passes through the top ofth e c amber.

- Preferably, in the use of, the present invention, the overfiow'pipe;; i5 of the radiator constitutes the means oiifieonnection between T the latter and the pipe 10, being coupled to the pipe 10 as at 16 With the condenser chamber 14 there is connected an exp'ansible bulb 17 having a neck 18 which engages a nipple 19 connected to the top of the condenser ohamber, the nipple 19 andthe neck 18 placing the bulb interiorly in communication with the condenser chamber.

As the radiator contents rise in temperature, the vapor passes through-the pipe 1.0 and into the condenser chamber 14, where it condenses and ejects therefrom any air contained in the chamber which passes into the 1926. Serial No. 117,558. 4

bulb 17 which may be of rubber or any other readily expansible material. As long as the vapor remains in the pipe 10, however, there is no tendency to return the condensate contained in the condenser chamber 14: to the radiator, but when the temperature of the radiator contents drops and, the amount of vapor produced is reduced,-the vapor begins to condense in the pipe 10, and the atmospheric pressure on the exterior of the bulb 17' serves to compress the latter and,-there- .fore, toreturn. to the radiator through the pipe 10 the liquid condensate contained therein. I

- The device also serves as an overflow to. take care of the expansion of the radiator contents and,,'by virtue of the bulb 17 functions to return the overflow to the radiator upon contraction of the contents due to cool mg, as when the vehicle motor is stopped.

The condenser chamber 14 is mounted at a remote point from the radiator 11, thus providing for a long length in the pipe 10 and the exterior surface of this being exposed to the air, condensation begins when the vapor enters this pipe and the chamber 14. functionsmainly as a trap for the condensate. I I

The invention having been described, what is claimed as new and useful is:

,. '1. A device for the purpose indicated comprising, in combination with a radiator, a

condenser comprising a closed chamber disposed at a point remote from. the radiator, apipe connected with the overflow of the radiator entering the condenser chamber and terminating adjacent the bottom thereof, and an expansible airchamber connected with the condenser chamber adjacent the top thereof.

2. A device for the purpose indicated comprising," in 'pprpbinationwith a radator, a

condenser" "shame-ma pipe connecting the condenser-chamber withthe radiator, and an expansible'" air. chamber in communication with the o'onde r chamber, the said air chamber consistingof a bulb formed of expansible materiall havingQ aI'neck connected 1\gvith a ripple formed on the condenser chamer. i

In testimony whereof he afiixes his signature. 1
